Question Advice needed for the best value 450-600W PSU

Hello everyone,

My PC specs is:
- J&W JW-A870T-UC3 mobo
- AMD Phenom II X4 955 3.2 GHz processor
- 4x 4 Gbytes DDR3 RAM
- AMD Radeon 5670 HD now, but planning to upgrade to nVidia GTX 750 or 760
- 3x SATA 7200rpm Harddisks
- planning to add 1x SSD
- Pioneer IDE DVD-RW
- 2x 12" + 2x 8" casing fans
- 4x USB 2.0 devices (webcam, external 7200rpm HDD, flashdisk, etc)

I'm looking for the cheapest but with good quality of 450-600W PSU that's suitable to my PC specs. I'm not sure about the exact power requirements; I've used some power requirement calculators:
- http://www.extreme.outervision.com/p...ulatorlite.jsp
- http://support.asus.com/powersupply.aspx
- http://images10.newegg.com/BizIntell...age-Calculator

and their calculation results are different from each other's, so I don't know which one to follow.

Thanks in advance for your advice.

The most possibly I'll buy from a local computer shop in Jakarta, Indonesia.

It might also help to know your budget...

I did find a site selling PSUs in Indonesia, but they really only had Enermax and Corsair. Not even their best models.

The best choices look to be:

Enermax Revolution 87+ 650W for Rp 1,920,000

Corsair RM650 650W for Rp 1,775,000

The Enermax seems to be a little better than the Corsair, from what I can find... but it's also a somewhat dated design and a lot more expensive from what I'm seeing here.

The RM650 has the lower price and will work, but I wouldn't be recommending it if you could get something like an AX or HX in a similar price range.

If you want an assurance of quality, you could pay Rp 3,100,000 and get an AX760i, but that would be overkill. It's just that all the lower wattages I see available are using dated and lower-end designs.

But I'm just guessing at what's available in your country based on this site. If your local retailer has a better selection, there might be better recommendations possible.

It's also worth noting (after a currency conversion) that all these designs are marked up to a bit more than they're really worth. I know that in some countries, you can haggle the retailer into coming down on the price. If you can, you should try to talk your way into at least a 15-20% discount. For the price they're asking, you really should be getting something a lot better than what you are getting.

I don't think you'll need 600W for even a GTX 760. The 750 uses the maxwell architecture, with a 60W TDP. The CPU has a 125W TDP. A solid 450W would run that.

Thanks everyone!

It's true that my choices are limited.
I've seen reviews on some good PSUs on the net, but many of them are not available in Indonesia.

Here are my possible options:

I'm currently using AMD Radeon 5670 HD. I hope the PSU I'll buy will be adequate for this old card too.

NVidia does recommend at least a 500W PSU for the GTX 760, though. I don't see a good reason to go under that number unless he confirms he's going with 750.

And from what I'm seeing, most of the units that are less than 650W are older/inferior designs in his country. I get the feeling most of it is junk.

The only two less than 650W that look "okay" are the Corsair RM550 and the Thermaltake Toughpower 80+. Below that, you only have the CX/VS/CS series which are worse than the RM series, and some no-name stuff by a company called Viper which lacks PFC.

While 450W may be enough to run his rig, I wouldn't trust the design of most of the 450W PSUs I saw on that site, at any wattage.

EDIT: Just checked the Rakitan list the OP linked.

The majority of the Seasonic units (like the S12II), the Super Flower Golden Green, and the Super Flower Leadex units should ALL be fine.

Just pick something 500W or above, within your price range. The Super Flower SF-550P14XE Golden Green (Gold) looks good to me, in particular.

That company has a much better selection.

Also, that old Radeon card of yours consumes equal or less power than the ones you're looking at.

Those two retailers have the Seasonic S12II/M12II 520W and G-550. Both of those would be good options. The SF Golden green would also be good. The CoolerMaster Silent Pro Gold 550W would a decent option too.

Cooler Master G550M, also.

If you have a choice between Golden Green and Golden Green HX, I would choose the non-HX model as they are superior in some ways.
